Thus, the asphalt section is based on a subgrade strength that is significantly less than the user input value and streerpave different from the subgrade strength used in the concrete design. The Asphalt Institute and many other well-established asphalt pavement industry associations have invested significant amounts of capital, time and effort in bringing the transportation industry credible, high value engineering tools, technology and information regarding asphalt pavement.
This software utilizes new engineering analyses to produce optimized concrete pavement thicknesses for city, municipal, county, and state srteetpave. StreetPave 12 is available as a free download and may be used without a license for up to 30 days.
American Concrete Pavement Association StreetPave v12
Stretpave the numbers shown in this LCCA chart are accurate, a 6. After the day trial period, you will need to purchase a license to continue using your copy of StreetPave Why would you use a concrete thickness program to design an asphalt pavement?
StreetPave covertly applies an additional and inappropriate factor of safety unbeknownst to the user, which results in excessive asphalt thickness. Likewise, the concrete pavement industry promotes their product by developing tools for strertpave concrete in pavement applications.
Streetpave inappropriately reduces the single subgrade modulus value that is input by the user prior to running the asphalt design calculation.
If the user streeetpave not access a secondary help screen, he will not be aware that the single M R design value was reduced.
Using aggregates effectively in a mixture is the essence of optimized graded concrete. StreetPave 12 is the latest in jointed plain concrete pavement thickness design.
The problem with this description is that the claim of equivalent asphalt and concrete sections is false. StreetPave takes the single subgrade strength value input by the user only one value is allowed and inappropriately reduces it prior to running the asphalt thickness design calculation.
The information on the following website is focused on well-graded aggregates for concrete and includes a recommended Specification for Optimized Graded Concrete Pavement. With one pavement design tool, you can design equivalent concrete and asphalt sections and evaluate the best possible solution s for your pavement needs.
No similar reduction is performed with the concrete design. Common sense and experience with pavement performance for many similar lightly traveled residential streets makes such a thick pavement highly unlikely and over-designed. Although the concept of proportioning aggregates may seem very basic at first, it can be very difficult to achieve the required workability.
The second practice simply allows the pavement designer to assess all known subgrade condition information and then apply conservative engineering judgment to assign a single Design Subgrade MR value to be used with the design curves. In a recent ACPA marketing brochure, StreetPave is used to design equivalent concrete and asphalt pavement sections for a residential street. One can see the differences are not trivial, with 37 percent additional asphalt thickness.

The ACPA promotional literature provides a snapshot of the results for a lightly traveled residential street as shown in Figure 2 below. This procedure is based on normal statistical variation and is clearly described in our MS-1 manual, SW-1 software and Research Report To apply the patch, download and run the. This forced reduction is unseen and does not occur as a separate, noticeable step, but only as a hidden part of calculating the asphalt pavement thickness. BCOA-ME is the product of a multi-state pooled fund project to develop a mechanistic based concrete overlay of asphalt pavement design.

Optimized Gradations Using aggregates effectively in a mixture is the essence of optimized graded concrete. If you have an earlier version of StreetPave, you may update to the most current version by applying StreetPave v1.
Design professionals should use these sources exclusively for their asphalt pavement design needs. The synthesis may be used as a reference for state agencies that are creating or updating their roundabout and intersection control policies.
This informative publication summarizes roundabout policies, guidance, and practices within state departments of transportation as of The LCCA chart infers that a 6. Resilient Modulus Input The Asphalt Institute methods allow the pavement designer to use one of two practices to determine a single Design Subgrade Modulus M R value that is used in conjunction with the thickness design curves.
It includes an asphalt cross-section design process based on the Asphalt Institute method to create an equivalent asphalt design for the load carrying capacity requirement. Buncher, Blow and Walker are engineers with the Asphalt Institute.
