Use of Secant Shear Modulus for Rutting Potential Assessment of Indonesian Wearing Course Mixtures
Since shear modulus (G) indicates a resistance to shear deformation, the property should be essentially considered to evaluate the rutting potential. This study discusses a criterion of G for Indonesian wearing course mixture (IWCM) design. Simple unconfined compression test was conducted to calculate secant shear modulus (G-sub-s) of IWCM. G-sub-s is a ratio of shear strength to shear strain. The wheel tracking test was conducted to verify validity of G-sub-s as a rutting potential index of IWCM. G-sub-s could rank the laboratory rutting performance of the designed mixtures as well as dynamic stability (DS). A relationship between G-sub-s and DS suggests that over 28 MPa in G-sub-s is equivalent to more than 800 cycles/mm in DS, within the scope of materials sources used in the present study. G-sub-s can be one of rutting potential indicators of IWCM.
