• Abstract:
  Stormwater quantity control is an important issue that needs to be addressed in roadway and ancillary transportation facility design. ; Pervious concrete has provided an effective solution for storm runoff for parking lots, sidewalks, bike trails, and other applications. It ; should be readily adaptable for use on roadway shoulders. Being a relatively new material for use in pavement for roadways, there is a ; lack of knowledge of the strength and behavior of pervious concrete slabs. While standard procedures for rigid pavement design with ; Portland cement concrete have been recommended, there are fundamental differences with pervious concrete pavement. These include ; a variation in concrete strength and stiffness through the depth of a slab and differences in the subgrade. Also, the main concern for a ; shoulder is the need to withstand wheel loadings from encroaching truck traffic. Both the strength of the pervious concrete pavement ; and the interface with the mainline pavement must be evaluated. Typically, tiebars are used at the interface to connect the shoulder and ; mainline slabs. The capacity and durability of pervious concrete at the tiebars is unknown, and steel reinforcing may not be an option with ; pervious systems. While full scale testing of pervious concrete pavement is desirable, a preliminary evaluation can be performed quickly ; and economically through computer simulation. The Finite Element Method is a proven technique for the evaluation of solids and ; structures. With this approach, a number of loading scenarios can be applied to various pavement configurations to determine pavement ; capacity and evaluate the importance of connections with tiebars. The results of these analyses can be used to guide a full-scale testing ; program and help develop design procedures.
