Abstract
Block pavements (BPs) can be of different types depending on applications and provide certain advantages in many instances. Among BPs, permeable concrete block pavements (PCBPs) play a vital role in sustainable drainage system and help the growth of trees and vegetations in urban environment. With the expansion of the usage of BPs from parking lots to heavier trafficked areas and owing to changing climatic conditions, it is necessary to develop guidelines for their designs and constructions. With this objective, ten different types of BPs were investigated in an accelerated pavement testing facility using a heavy vehicle simulator (HVS). The surface rutting developed during the load applications were measured. The impact of moisture was also investigated by raising the ground water table during the tests. By comparing the rutting performances of the BPs to a reference BP structure, the layer thicknesses of these BPs were adjusted using a pavement design software to attain the same rutting performance as the reference structure. Based on these analyses, design tables for BPs for Swedish conditions were developed. In this paper, the results from the HVS tests and the methodology used for the development of the design tables are summarized.
