  1. SUBGRADE STABILITY and LIME TREATMENT APPLICATIONS at OMP Marshall Thompson, P.E. Professor Emeritus – CE University of IL @ U-C

  2. SUBGRADE SOIL PROPERTIES *STRENGTH (CBR/QU) * MODULUS * RUTTING RESISTANCE

  3. 0.5-INCH RUT / CBR - 6 0.5 INCH / CBR -6

  4. SOIL COMPACTION

  5. MATERIAL COMPACTION

  6. MATERIAL COMPACTION

  7. MOISTURE – DENSITY - CBR • UofIL / IDOT PROCEDURE • COMPACT MOLD • CBR ON “FINISHED” MOLD

  8. 25 20 15 Required Thickness Above Subgrade (inches) 10 Remedial procedures not needed Remedial procedures optional 5 Remedial Procedures Required 0 0 1 2 3 4 5 6 7 8 9 Subgrade CBR IMPROVED MATERIAL COVER REQUIREMENTS

  9. CE CONE PENETROMETER

  10. CBR = CI / 40

  11. LOG (CBR) = 0.84 – 1.26 LOG (PR) PR – Penetration Ratio (inches/blow)
