| Abstract | The objective of this study is to assess horizontal drilling as an alternative to pilot tunneling in geological investigation prior to the design and construction of highway tunnels and to identify means to increase the penetration capability and accuracy and decrease the cost of horizontal drilling. This volume evaluates the potential for improving horizontal drilling capability by: (a) more efficient use of existing equipment, modification of existing equipment, and adaption of equipment not previously employed for horizontal drilling and by (b) developing new horizontal, drilling equipment and techniques. Within these guidelines, means are identified to decrease the cost and/or increase the performance capability of horizontal drilling. Development plans to implement these improvements are outlined and estimates of development costs are indicated. This is the third of three volumes. Volume I is published as FHWARD 75-95, subtitle: A State -of -the -Art Assessment. Volume II is published as FHWA -RD-75 -96, subtitle: Estimating Manual for Time and Cost Requirements. |
