Revisions and additions to Part I (specifications) and Part II (test methods) of the Eleventh Edition of Transportation Methods are presented. The interim specifications include revisions to such subjects as oil asphalt filter, zinc coated corrugated iron or steel culverts and underdrains, welded steel wire fabric for concrete reinforcement, cut-back asphalt, portland cement and steel forgings, and carbon and alloy for general industrial use. Mild-to-medium strength carbon-steel castings; copper sheet, strip, plate and rolled bar; and requirements for delivery of rolled steel plates, shapes, sheet piling and bars for structural use are the subject of other interims. Revisions are also proposed for M 168-751; M 169-751; M 177-751; M 181-751; M 196-751; M 198-751; and M 205-751. Other revisions relate to columbium-vanadium steels; epoxy adhesives; reinforced concrete culvert, storm drain, and sewer pipe; field applied coating; precoated galvanized steel; thermoplastic traffic line. Interims are issued for plastic drainage pipe or tubing; alloy steel bolts; and dowel bars. The interim methods revisions relate to sieve analysis of mineral filler; solubility of bituminous materials and organic solvents; flash and fine points; softening point of asphalt and tar in ethylene glycol; and organic impurities in fine aggregate. Replacements are proposed for T 78-74; T 89-68; T 196-74; T 201-74; T 228-68; The liquid limit of soils, aggregate resistance to abrasion, specific gravity of soils, extraction of bitumen, air-entraining additions to portland cement, and the air content of freshly mixed concrete are the subject of further revisions. Revisions are also proposed of articles covering the viscosity of asphalts, thin-walled tube sampling of soils, diamond core drilling, specific gravity of semi-solid bituminous materials, skid resistance, lock seam corrugated pipe, hollow stem auger borings, soil bore pressure, and testing coated dowel bars.
