A SPECIAL PRESSURE METER AND PRESSURE METER TEST FOR PAVEMENT EVALUATION AND DESIGN

A special pressure meter and pressure meter test procedure have been developed specifically for use in pavement engineering. The probe of the pavement pressure meter is short and monocellular; single tubing is used; and the control unit is simple and designed for performing strain controlled tests. The probe is inserted in a predrilled 35-mm (1.38-in.) diameter hole and tests are performed every 300 mm (11.8 in.) down to a depth of 2000 mm (78.7 in.). A test curve is obtained at each interval of depth and a recompression modulus is obtained from each test curve. The recompression modulus profile can be used empirically or theoretically for the design of new pavements, for the evaluation of existing pavements, and for the design of overlays. The pavement pressure meter gives a direct evaluation of the deformation characteristics of each of the pavement and subgrade layers (except the surface course) at reduced cost. The apparatus is portable, easy to transport, and relatively inexpensive; the test itself is relatively rapid. (AUTHORS)
