Web2.2 Interlock Critical to the structural performance of segmental concrete pavements is the concept of interlock between the units. Figure 1 demonstrates the three types of interlock that must be achieved; vertical, rotational, and horizontal. Vertical interlock relies primarily on shear transfer of loads to WebJan 1, 2015 · For calculation of the aggregate interlock forces developing at the critical shear crack, its shape and kinematics are governing [13,14,49,38] together with the size …

WebJan 1, 2009 · The main mechanism by which geogrids reinforce unbound aggregate base and subbase layers of flexible pavements is the geogrid aggregate interlock. Geogrids prevent aggregate material from moving laterally under applied wheel loading; this enhances local strengthening and stiffness in the base layer. Webterm enhanced aggregate interlock and the joint spacing is to be from 10 to 15 feet, the minimum amount of fiber con-sidered for concrete with typical shrink-age properties is 40 … WebComparisons between potential aggregate interlock for various crack and undoweled joint faces can be made by multiplying VSTR by the “effective” pavement thickness. The effective pavement thickness refers to only that portion of the fractured slab face that contains crack texture. For instance, the effective pavement thick- butter almond thins
