9-02.1(8) Flexible Bituminous Pavement Marker Adhesive

Flexible bituminous pavement marker adhesive is a hot melt thermoplastic bituminous material used for bonding raised pavement markers, recessed pavement markers, and flexible guide posts to the pavement. The Contractor may submit a maximum of two flexible bituminous pavement marker adhesive lot samples per Contract for testing by the Contracting Agency at the Agency’s expense. The Contractor shall allow 21 calendar days for the Contracting Agency to test each flexible bituminous pavement marker lot sample from when the sample is accepted by the State Materials Laboratory in Tumwater, Washington. The Contractor may submit additional flexible bituminous pavement marker lot samples for testing by the Contracting Agency. All costs for the sampling, documentation and testing of the additional flexible bituminous pavement marker lot samples will be deducted from the Contract. The Contractor agrees to authorize the Engineer to deduct the documentation and testing costs from money due or coming due to the Contractor. The Contractor shall allow 45 calendar days for the Contracting Agency to test each additional flexible bituminous pavement marker lot sample from when the sample is accepted by the State Materials Laboratory in Tumwater, Washington. When the Contractor submits multiple flexible bituminous pavement marker lot samples for testing, the Contractor shall provide a written priority for testing the samples. Page 9-6 M 41-10
