3. For a dual carriageway new road scheme, the average annual daily flow (AADT) of one way traffic is 24,000; 2% are commercial vehicles. No channelisation is expected to occur. Design a foundation and bound layers of a pavement. The subgrade surface modulus = 40mpa = 4%CBR. State any assumptions made, including the choice of design method and sketch a cross section of the final pavement design.

(N.B. there are hundreds of potentially correct designs depending on the choices of design methods and materials. Any submissions that include identical designs may be investigate for potential collusion).

A firm’s annual credit sales are $1.34 million, with 51% of its daily average paid out in purchases. It usually takes the company 30 days to meet its purchasing obligations. This payment pattern has not changed in recent years. However, the firm’s commitment to accounts receivable has shifted based on its current annual net income of $28k which meets the 2.3% required return, anticipated by senior management a year earlier. Normally, the firm collects its accounts in 24 days, an...
