Effect of Pavement Design on Cratering Damage from Penetrating Weapons
The objective of this research effort was to study the effect of various pavement design on the cratering damage caused by penetrating weapons. These data were to substantiate data from previous testing performed by the Air Force Weapons Laboratory (AFWL). Conventionally jointed Portland cement concrete (PCC) pavements; continuously reinforced concrete pavements (CRPC); fiber reinforced concrete pavements (FRCP); and PCC pavements with asphaltic cement concrete (ACC), PCC, and CRPC overlays were used in this study. Pavement thickness, joint and overlay design, and the underlying materials were varied. Twenty-eight tests were conducted on the pavement sections. In 26 of these tests a 15-lb charge of C-4 explosive was used; a 45-lb C-4 charge was used in the other two tests. The two 45-lb C-4 tests were conducted on configuration II - silty sand where only a slight amount of damage was sustained from the 15-lb C-4 explosive. Damage quantities including concrete blown out and severely damaged concrete were measured. From the study of joint designs, it was learned that the contraction joints are quicker to repair since it is easier to break out the concrete when dowels are not involved. Portland cement concrete pavements with ACC and PCC overlays sustained more damage. Configurations II on the clay subgrade sustained a slight amount of damage; configuration II on the silty sand subgrade sustained the least amount of damage. (Author)
