The surfacing on a new access road into a subdivision is designed to be a primerseal covered with a dense graded asphalt wearing course. The asphalt surfacing is $10$mm dense graded asphalt placed at an average thickness of $30$mm$.$ The access road consists of two carriageways divided by a narrow paved median, and each carriageway has one $4\mathrm{.}0$m width traffic lane and a $2\mathrm{.}5$m wide parking lane on the left hand side. Estimated to be about $1800$ AADT, consisting of $80\%$ cars and $20\%$ delivery vehicles, including some semi$-$trailers mainly used to supply building materials for new houses. The asphalt wearing course is specified to be placed within $7$ to $10$ days after applying the primerseal. The primerseal is programmed to be done within the next few days and the weather forecast is for fine but cool conditions with light to moderate winds, and the chance of rain within the next $10$ days is very low. Explaining the reasons for your selection and any assumptions made: i$.$ Select an appropriate type and grade of primerbinder. $*$ ii$.$ Select a suitable size of aggregate. $*$ iii. Design the rates of application of primerbinder and aggregate spread rates. $*$The surfacing on a new access road into a subdivision is designed to be a primerseal covered with a dense graded asphalt wearing course.
