Several researchers have developed regression equations to predict the subgrade modulus, E SG, from plate load and deflections measured at distances from about 24 in. The M-E design program developed in-house seems to estimate the HMA overlay thickness reasonably well to achieve long-lasting performance of HMA-overlaid rubblized PCC pavements. Backcalculation software for pavement manual Backcalculation software for pavement full (1200 mm) from the center of the plate load. The average rubblized PCC layer coefficient and backcalculated modulus of the rubblized layer in Iowa were found to be 0.19 and 539 MPa (78 ksi), respectively. This paper describes a field study undertaken to investigate the performance of rubblized pavements in Iowa, which includes characterization of the rubblized Portland cement concrete (PCC) layer (layer coefficient and modulus) using a neural networks-based layer moduli backcalculation program. The most important aspect of the design procedure is to characterize the rubblized concrete layer in terms of a layer coefficient and modulus for the empirical and the mechanistic-empirical (M-E) pavement design methods. Institute) (Liu and Scullion 2001) was available for free to state and local. The design of the structural overlay thickness for rubblized projects is difficult as the resulting structure is neither a true rigid pavement nor a true flexible pavement. Table 2.1: Key Features of Popular Backcalculation Software Programs. Rubblization is considered one of the sustainable surface preparation techniques before placing a hot mix asphalt (HMA) overlay that involves breaking the concrete pavement into pieces.
