บทคัดย่อ
ปัจจุบันประเทศไทยมีถนนผิวทางแอสฟัลต์คอนกรีตทั้งหมดร้อยละ 94.48 ของถนนทั้งหมด ด้วยจำนวนที่มากและต้องการพัฒนาให้ผิวทางมีสมรรถนะที่ดีขึ้น จึงจำเป็นต้องมีการทดสอบคุณสมบัติทางวิศวกรรมของแอสฟัลต์คอนกรีตก่อนการทดสอบต้องมีการบ่มตัวอย่างให้ได้อุณหภูมิที่กำหนด ระยะเวลาที่ใช้ในการบ่มตัวอย่างในงานวิจัยที่ผ่านมามีตั้งแต่ 3 ถึง 24 ชั่วโมง โดยผู้วิจัยส่วนใหญ่ใช้ระยะเวลาบ่มตัวอย่าง 24 ชั่วโมง ทำให้การใช้เครื่องมือในห้องปฏิบัติการใช้เวลานานมีผลให้การวางแผนการใช้งานเป็นไปอย่างไม่มีประสิทธิภาพ งานวิจัยนี้นำเสนอแบบจำลองในการหาระยะเวลาที่เหมาะสมสำหรับการบ่มตัวอย่างแอสฟัลต์คอนกรีตซึ่งผสมระหว่างหินปูนกับวัสดุเชื่อมประสาน AC 60-70 และ PMA ที่อุณหภูมิต่างๆ ผลการทดสอบระบุว่าระยะเวลาที่ใช้ในการบ่มตัวอย่างให้ได้อุณหภูมิ 40 องศาเซลเซียส คือ 3 ชั่วโมง 40 นาที การตรวจสอบความถูกต้องทำโดยการทดสอบกำลังรับแรงดึงทางอ้อมและการทดสอบมอดุลัสคืนตัวแบบให้แรงดึงทางอ้อมของการบ่มก้อนตัวอย่างระยะเวลา 3 ชั่วโมง 40 นาที เปรียบเทียบกับการบ่มก้อนตัวอย่างระยะเวลา 24 ชั่วโมง ผลการศึกษาแสดงให้เห็นว่าไม่แตกต่างอย่างมีนัยสำคัญ (p-value มากกว่า 0.05) ดังนั้นระยะเวลาในการบ่มตัวอย่างแอสฟัลต์คอนกรีตเพื่อให้ได้อุณหภูมิ 40 องศาเซลเซียส ถูกลดลงจาก 24 ชั่วโมงเป็น 3 ชั่งโมง 40 นาที ทำให้การใช้ห้องปฏิบัติการมีประสิทธิภาพมากขึ้น
