asphalt pavement design thickness
Pavement Design - Thickness DesignPavement Design - Thickness Design. The thckness design of the pavement is the determination of the overall thickness of the road and the thickness of the individual layers. This is of course dependant on the type of material chosen for the road. This is explained in more detail below.
Parking Lot Design - vaasphalt.orgMinimum pavement thickness designs are given for both small parking areas (50 passenger car stalls or less) and larger facilities (over 50 passenger car stalls). In addition, comparable designs are given for both full­-depth asphalt pavement (pavements using asphalt concrete for both base and surface courses) and asphalt over an aggregate base.

Pavement thickness design evolves with latest software ...Pavia Systems, with sponsorship from the Asphalt Pavement Alliance (APA) and its constituent members, has developed free online pavement thickness design software called PaveXpress. The software simplifies the process of using both the 1993 AASHTO design guide for asphalt pavements and 1998 AASHTO supplement for concrete pavements.

Residential Street Design - vaasphalt.orgIn establishing the pavement design, consideration should be given to using a layered asphalt pavement with the final surface being placed after home construction has been completed. This type of construction technique permits the patching of any areas of pavement failure prior to final surfacing.
Calculate proper pavement thickness with free online tool ..."Among all design variables, the asphalt structural coefficient has the strongest correlation to pavement thickness," stated Dr. David H. Timm, P.E., principal investigator for the project. "Modern advances in pavement materials and construction techniques allow flexible pavements to carry more traffic with less thickness, which leads to ...
Driveways - Asphalt PavementAs an option, some contractors use 6 to 8 inches of compacted aggregate, or gravel, as a base for 3 inches of asphalt pavement. "We recommend full-depth asphalt for driveways," says Kent Hansen, former NAPA Director of Engineering. "We calculate that asphalt can replace aggregate on a ratio of 1:3 in thickness.

Gradation is intermediate between base and top.
NHI-05-037 - Geotech - Federal Highway AdministrationAppendix C: 1993 AASHTO Design Method C.1 Introduction. The AASHTO Guide for Design of Pavement Structures (AASHTO, 1993) is the primary document used to design new and rehabilitated highway pavements. Approximately 80% of all states use the AASHTO pavement design procedures, with the majority using the 1993 version.
Pavement Thickness Design - intrans.iastate.edufor pavement thickness design. A newer design program called the Mechanistic-Empirical Pavement Design Guide (MEPDG) is available, however, it is costly and requires a great deal of data to be effective. The MEPDG does not generate a pavement thickness, it is set up to analyze the failure potential for a given thickness design.
2016 Asphalt Pavement Design Guide - wispave.orgEconomical—Asphalt pavements can be designed for a range of intended uses. There's no need to use a prede-termined pavement thickness when conditions permit otherwise. Asphalt also permits the use of local materials, which results in cost savings.
