Material TypeMATFilter media (granular filter material) placed behind abutment / independent retaining wall -Callout '600 THK. FILTER MEDIA' on both the abutment section (SECTION A-A, 1:150) and the general elevation (1:300); object described as 'granular filter media'. No gradation specification or material grade is printed in the readings.The material designation is taken from the drawing's own callout; the finer classification (granular) is the annotated description, but no specification clause or gradation is given, hence the material is identified only generically.readcheckp2 · p02_r07p2 · p02_r02p2 · p02_r07 section through wall abutment with bored piles

  "description": "Longitudinal section (SECTION A-A, scale 1:150) through abutment A2 of a bridge, showing the deck slab and box/girder end seated on a pot-PTFE bearing with an RCC seismic stopper, the expansion joint and dirt wall, and the 1500 thick abutment stem carried on a pile cap with four 1200 dia bored cast-in-situ piles at 3600 centres over a 12300 overall width. Behind the abutment the drawing documents 600 thk filter media, an independent retaining wall with its own footing (dashed), embankment fill at 1:2 slope with stone pitching, and a tapered approach slab element at the left. The girder is cut by a break line on the left, so only the abutment end of the superstructure is within this crop; no reinforcement detailing or elevations/stations are shown."

It documents the superstructure (precast PSC girders, deck with continuity over the pier, RCC crash barriers, pot-PTFE bearings marked FR/FX, expansion joints) and the substructure/foundation (wall type abutments, pile caps on 1200 mm dia cast-in-situ piles, approach slabs on PCC leveling course, independent retaining walls with filter media, stone pitching and launching apron). A tabulated schedule below gives chainages, finished road levels and ground levels at LHS/RHS for each of A1, P1 and A2; the notes block at lower right is partially cut off at the crop edge."

Behind the abutment it documents the approach embankment with 1:2 batter, stone pitching, 600 thick filter media, an independent retaining wall with its own footing, and the approach slab at left. Below ground the abutment is founded on a pile cap 12300 long with four 1200 dia bored cast-in-situ piles at 3600 centres and 750 end offsets, drawn in hidden line."
