1044SUBSURFACE DRAINAGE MATERIALS

AGGREGATE FROM CRUSHED CONCRETE 1043 -1 GENERAL Aggregate from crushed concrete is a recycled product made by crushing concrete obtained from concrete truck clean out, demolition of existing concrete structures or pavement, or similar sources , which have been processed at a crus hing facility. It does not include concrete pavements that are rubblelized, broken or otherwise crushed in place on the roadway, without having been processed at a crushing facility. The crushed material must meet all sources approval requirements described in Sections 1005 and 1006 with the exception of the sodium sulfate test requirement. Sampling and acceptance for the determination of gradation, LL and PI will be performed as described in the Aggregate QC/QA Program Manual and the Aggregate Sampling Manual . 1043 -2 AGGREGATE BASE COURSE AND SELECT MATERIAL CLASS IV The material shall meet the ABC gradation. The LL of the material shall be raised 5 points to no more than 35. 1043 -3 AGGREGATE SHOULDER BORROW The material shall meet Section 1019. 1043 -4 CLEAN COARSE AGGREGATE FOR ASPHALT The material shall meet the gradation of a standard size in Table 1005 -1 and Subarticle 1012- 1(B). Use of the material shall be approved by the Engineer, and the mix shall meet all requirements. 1043 -5 CLEAN COARSE AGGREGATE FOR CONCRETE The material shall meet the gradation of a standard size in Table 1005 -1 and Subarticle 1014- 2(C). Use of the material is restricted to Class B concrete mixes only. Use of the material shall be approved by the Engineer, and the concrete shall meet all requirements. SUBSURFACE DRAINAGE MATERIALS -1 SUBDRAIN FINE AGGREGATE Subdrain fine aggregate shall meet Class III select material, Type 1 or Type 3. -2 SUBDRAIN COARSE AGGREGATE Subdrain coarse aggregate shall meet Class V select material . -3 PIPE AND FITTINGS Pipe and fittings may be, at the option of the Contractor, either concrete, corrugated steel, bituminized fiber or corrugated plastic. -4 CONCRETE PIPE AND FITTINGS Non-perforated concrete pipe and pipe fittings shall meet AASHTO M 86 for standard strength nonreinforced concrete pipe.
