D. solit•tube sampler, except where noted. TW indicates thin - <br />well undisturbed temple. <br />BPF: Numbs I idicaN blows per foot recorded in standard penetration salt, alto known as "N" value. The sampler <br />is Nt 6" Into undisturbed soil below the hollow -sum suer. Driving resistances an then counted for second <br />and third 6" incrienants and added to get OFF. Wisre they differ significantly, they we reported in the <br />follawing form — 2112 for the second and third 6" incre rernts reepeetively. <br />WH: WH wndicates that asmpler penetrated soil under weight of hemmer and rods alone, driving not required. <br />NOTE: Ail tan run in scawdence with applicable ASTM stsndwdo. <br />omen <br />ENGINEERING TESTING <br />
