Innovative maintenance procedures and maintenance materials used by the Texas Highway Department and developed by district maintenance personnel are briefly presented. Procedures discussed involve maintenance methods and equipment associated with pavement and shoulder repair including rapid repair of bridge deck failures, maintenance equipment with hot storage capabilities and unsurfaced shoulder repair with mechanized operations. The use of a one-man, truck-mounted herbicide sprayer; mechanized mulching and seeding operations for erosion control; mechanized litter gathering equipment; and a culvert cleanout process using a dog are also discussed. Specialized materials used in Texas maintenance operations include lightweight aggregate mixtures for seal coats, overlays, plant-mixed seals, bridge deck overlay, and hot-mixed, cold-laid patching materials. A brief description of these practices together with limited economic data is presented for comparison with other state highway department practices.
