ASTECH engineer details chip‑seal methods, recommends 10% oil‑price buffer

Tom Wood of ASTECH presented to the Silver Creek Township Board on chip‑seal bidding methods and industry practice for oil-and-rock application rates, telling supervisors that traffic volumes and embedment affect long‑term performance. He recommended that the township include an allowance for oil-price volatility when soliciting bids: "recommended adding 10% buffer to proposals," Wood said.
