She is known for her independent films and documentaries, including one about Alexander Graham Bell.

Benkelman further reinforced the concept of limiting pavement deflections for design purposes. When were the first roads built in America? In summary, the structural design of asphalt and PCC pavements up to the 1950s (where this section stops) was a function of an evolutionary process beginning with the Romans then Telford and Macadam. Rules are one method of controlling traffic, however, many inventions are used to support traffic control. Contraction joints in plain PCC slabs were recommended every 4.6 to 6.1 m. Load transfer devices (dowel bars) were used by about one-half of the states. The test provides a quick method of comparing base and subgrade materials. Essentially, the maximum aggregate size was 75 mm ranging down to dust. Thus, asphalt concrete mixes thereafter were more oriented to the smaller maximum aggregate sizes.

Much like a modern highway, it did not go through less important towns along the way, and it largely ignored geographical obstacles. Asphalt concrete is a simple product in appearance produced primarily by adding asphalt cement to sand and rock. The hydraulic lime was produced by heating limestone above 850 C thereby driving off CO2 and converting the limestone to CaO. (after Collins and Hart [1936]). It was estimated that this system would support a load corresponding to 88 N/mm (500 lb per in. Lots of work has gone into the smooth, sturdy roads we take today. So, it should come as no surprise that Sir Walter Raleigh discovered a lake of asphalt when he arrived on the island of Trinidad in 1595. In the 1910 City of Seattle Standard Specifications, it was stated that an asphalt pavement shall consist of: Further, the asphalt cement in the asphalt paving mixture, shall be a solid, natural bitumen obtained from some natural deposit that has been in use in the paving industry for at least five (5) years., By 1919, the Seattle Standard Plans and Specifications contained the same definition for asphalt pavement (AC over PCC) but the asphalt binder could be, either a solid natural bitumen or a California oil asphalt that has been in use in the paving industry for at least five (5) years.. Apparently, blood (hemoglobin actually) is an effective air-entraining agent and plasticizer (given the mild Mediterranean climate the primary use was likely for workability). Actually, the road is a 6,000 year old walkway which was discovered in 1970 in a peat bog. Jaster, J., G.F. Schlesinger, J.S.
