Abstract: This paper presents a forensic investigation of selected Arizona specific pavement study (SPS) SPS-5 test sections. As courses pursue firmer sands with greater angularity and wider particle size distribution, the suggested depth may continue to increase, up to 8-10 inches in some cases depending on the sand and bunker design. Summary of Changes The owner/operators are highly qualified to NPTC standards and have a combined 17 years industry experience giving the ability to carry out work to the highest standard. This work will be carried out again in around 4 years time. A fairly common practice with Lombardy Poplars, this tree was having a height reduction to reduce the wind sail helping to prevent limb failures. . This British Standard is set out to follow, in broad terms, the sequence of a ground investigation from initial considerations through the phased design and implementation of an investigation programme and its reporting, to the continuing investigation during and after construction. The aggregate characteristics for the virgin aggregates, RAP, and the selected mixture gradation are shown in Table 1. 2000-2003 1997-2000 1992-1996 Hmu The amount of water content per unit volume of concrete may be determined from Table 4.
