He wrote a memorandum on his method in 1775, which became general practice in France. It involved a layer of large rocks, covered by a layer of smaller gravel. </p><p>By the late 18th and early 19th centuries, new methods of highway construction had been pioneered by the work of two British engineers: <a href="/wiki/Thomas_Telford" title="Thomas Telford">Thomas Telford</a> and <a href="/wiki/John_Loudon_McAdam" title="John Loudon McAdam">John Loudon McAdam</a>. Telford's method of road building involved the digging of a large trench in which a foundation of heavy rock was set. He designed his roads so that they sloped downwards from the centre, allowing drainage to take place, a major improvement on the work of Trésaguet. The surface of his roads consisted of broken stone. McAdam developed an inexpensive paving material of soil and stone aggregate (known as <a href="/wiki/Macadam" title="Macadam">macadam</a>). His road building method was simpler than Telford's, yet more effective at protecting roadways: he discovered that massive foundations of rock upon rock were unnecessary, and asserted that native soil alone would support the road and traffic upon it, as long as it was covered by a road crust that would protect the soil underneath from water and wear.<sup id="cite_ref-ColossusofRoads_11-0" class="reference"><a href="#cite_note-ColossusofRoads-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> Size of stones was central to McAdam's road building theory.

In virtually all modern mixes there will also be various admixtures added to increase workability, reduce the required amount of water, mitigate harmful chemical reactions, and for other beneficial purposes. In many cases there will also be Portland cement substitutes added, such as <a href="/wiki/Fly_ash" class="mw-redirect" title="Fly ash">fly ash</a>. This can reduce the cost of the concrete and improve its physical properties. The material is applied in a freshly mixed slurry and worked mechanically to compact the interior and force some of the cement slurry to the surface to produce a smoother, denser surface free from honeycombing. The water allows the mix to combine molecularly in a chemical reaction called <a href="/wiki/Mineral_hydration" title="Mineral hydration">hydration</a>. </p><p>Concrete surfaces have been classified into three common types: jointed plain (JPCP), jointed reinforced (JRCP) and continuously reinforced (CRCP). The one item that distinguishes each type is the jointing system used to control crack development. </p><p>One of the major advantages of concrete pavements is they are typically stronger and more durable than asphalt roadways. The surface can be grooved to provide a durable skid-resistant surface. Concrete roads are more economical to drive in terms of fuel consumption, they reflect light better, and they last significantly longer than other paving surfaces; but they have a much smaller market share than other paving solutions.<sup id="cite_ref-22" class="reference"><a href="#cite_note-22"><span class="cite-bracket">[</span>22<span class="cite-bracket">]</span></a></sup> Modern paving methods and design methods have changed the economics of concrete paving so that a well-designed and placed concrete pavement will be cheaper in initial cost and significantly cheaper over the life cycle.<sup id="cite_ref-23" class="reference"><a href="#cite_note-23"><span class="cite-bracket">[</span>23<span class="cite-bracket">]</span></a></sup> Another important advantage is that waterproof concrete can be used, which eliminates the need to place storm drains next to the road and reduces the need for a slightly sloped driveway to drain rainwater.

(material)">fatigue</a> (in a manner similar to <a href="/wiki/Metal" title="Metal">metals</a>), the damage done to pavement increases with the fourth power of the <a href="/wiki/Axle_load" title="Axle load">axle load</a> of the vehicles traveling on it. According to the <a href="/wiki/AASHO_Road_Test" title="AASHO Road Test">AASHO Road Test</a>, heavily loaded <a href="/wiki/Truck" title="Truck">trucks</a> can do more than 10,000 times the damage done by a normal passenger car. <a href="/wiki/Tax" title="Tax">Tax</a> rates for trucks are higher than those for cars in most countries for this reason, though they are not levied in proportion to the damage done.<sup id="cite_ref-60" class="reference"><a href="#cite_note-60"><span class="cite-bracket">[</span>60<span class="cite-bracket">]</span></a></sup> Passenger cars are considered to have little practical effect on a pavement's service life, from a materials fatigue perspective. </p><p>Other failure modes include aging and surface abrasion. As years go by, the binder in a bituminous <a href="/wiki/Wearing_course" title="Wearing course">wearing course</a> gets stiffer and less flexible. When it gets "old" enough, the surface will start losing aggregates, and <a href="/wiki/Macrotexture" class="mw-redirect" title="Macrotexture">macrotexture</a> depth increases dramatically. If no maintenance action is done quickly on the wearing course, <a href="/wiki/Pothole" title="Pothole">potholes</a> will form. The <a href="/wiki/Freeze-thaw" class="mw-redirect" title="Freeze-thaw">freeze-thaw</a> cycle in cold climates will dramatically accelerate pavement deterioration, once water can penetrate the surface. Clay and fumed silica <a href="/wiki/Nanoparticle" title="Nanoparticle">nanoparticles</a> may potentially be used as efficient UV-anti aging coatings in asphalt pavements. </p><p>If the road is still structurally sound, a bituminous surface treatment, such as a <a href="/wiki/Chipseal" title="Chipseal">chipseal</a> or surface dressing can prolong the life of the road at low cost.

A mechanistic-empirical design guide was developed through the NCHRP process, resulting in the Mechanistic Empirical Pavement Design Guide (MEPDG), which was adopted by AASHTO in 2008, although MEPDG implementation by state departments of transportation has been slow.<sup id="cite_ref-Li_Xiao_Wang_Hall_2011_pp._114–133_62-0" class="reference"><a href="#cite_note-Li_Xiao_Wang_Hall_2011_pp._114–133-62"><span class="cite-bracket">[</span>62<span class="cite-bracket">]</span></a></sup> </p><p>Further research by <a href="/wiki/University_College_London" title="University College London">University College London</a> into pavements has led to the development of an indoor, 80-sq-metre artificial pavement at a research centre called <a href="/wiki/Pedestrian_Accessibility_and_Movement_Environment_Laboratory" title="Pedestrian Accessibility and Movement Environment Laboratory">Pedestrian Accessibility and Movement Environment Laboratory</a> (PAMELA).

The "Seedling Miles," according to the LHA's 1924 guide, were intended "to demonstrate the desirability of this permanent type of road construction" and "crystallize public sentiment" for "further construction of the same character." Generally, the LHA worked with the Portland Cement Association to arrange donations of cement for the seeding mileage...The most famous "seedling" and one of the most talked about portions of the Lincoln Highway was the 1.3-mile "Ideal Section" between Dyer and Schererville in Lake County, Indiana. In 1920, the LHA decided to develop a model section of road that would be adequate not only for current traffic but for highway transportation over the following 2 decades. The LHA assembled 17 of the country's foremost highway experts for meetings in December 1920 and February 1921 to decide design details of the Ideal Section. They agreed on such features as: A 110-foot right-of-way; A 40-foot wide concrete pavement 10 inches thick (maximum loads of 8,000 pounds per wheel were the basis for the pavement design); Minimum radius for curves of 1,000 feet, with guardrail at all embankments; Curves superelevated (i.e., banked) for a speed of 35 miles per hour; No grade crossings or advertising signs; and A footpath for pedestrians.</q></cite><span title="ctx_ver=Z39.88-2004&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Ajournal&rft.genre=unknown&rft.jtitle=Federal+Highway+Administration+%28FHWA%29&rft.atitle=The+Lincoln+Highway&rft.date=2011-04-07&rft.aulast=Weingroff&rft.aufirst=Richard+F.&rft_id=https%3A%2F%2Fhighways.dot.gov%2Fhighway-history%2Fgeneral-highway-history%2Flincoln-highway&rfr_id=info%3Asid%2Fen.wikipedia.org%3ARoad+surface" class="Z3988"></span></span> </li> <li id="cite_note-31"><span class="mw-cite-backlink"><b><a href="#cite_ref-31">^</a></b></span> <span class="reference-text"><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238218222"><cite id="CITEREFKhazanovichLederleTompkinsHarvey2012" class="citation book cs1">Khazanovich, L.; Lederle, R.; Tompkins, D.; Harvey, J.T.; Signore, J.
