The contract is worth up to £200m over five years, starting in April 2014, and covers more than 500 miles of carriageway.
Spanish-owned Amey now has two ASC contracts. In August it was awarded the ASC contract in Area 6 (East Anglia).
Nationally, ASCs are replacing the existing arrangements, known as Managing Agent Contractor (MAC) contracts, and will form the basis of the delivery of maintenance and improvement services for most parts of England’s motorway and trunk road network.
The contract scope extends beyond routine maintenance to include scheme identification, value management, design and construction of schemes up to £5m and design and management of schemes in excess of £5m.
The Highways Agency says that ASCs will help to reduce the cost of road maintenance by 25% by 2015 by specifying the outcomes required and giving suppliers greater freedom on how to achieve those outcomes.
Amey chief executive Mel Ewell said: “The award of Area 8 supports our on-going strategy to grow our market share in this sector. The Highways Agency is a key client to Amey and this, along with the recently awarded Area 6 contract, strengthens our platform with the agency, providing us with significant opportunities to further develop this relationship and help move the industry forward.”
